Abstract: The applied software for predicting the distribution of flow units was developed with VB programming language on the basis of SuperMap control objects of geographic information system(GIS).This software integrated the functions of data management,spatial analysis and diagram visibility of SuperMap objects.The multiple reservoir properties for this software,such as lithofacies,porosity,permeability and net thickness,were stored by vector data objects of SuperMap.An integrated analysis of multiple parameters can be efficiently performed using the overlap analysis mode of this software.The new developed software was successfully applied to Weizhou Oilfield.The results show that the software can improve the division efficiency of flow unit.This software will be easily adapted to other situations,while changing the division criteria or the number of data/parameters involved.

Key words: flow unit division, prediction software, geographic information system, overlap analysis mode, secondary development control object, reservoir evaluation

摘要： 根据地理信息软件Super Map二次开发的控件,采用VB语言开发了预测储层流动单元平面分布的应用软件。该软件利用Super Map中的矢量数据集保存孔隙度、渗透率、砂体厚度等参数的等值线图,利用栅格数据集保存沉积微相分布图,利用开发的叠加分析模块快捷地综合分析用于划分流动单元的多项参数。该软件利用地理信息系统(GIS)软件强大的数据管理、空间分析和图形可视化功能,提高了储层流动单元划分的效率,增加了划分结果的真实性与客观性。利用该软件对涠洲油田沉积微相、孔隙度和渗透率进行了综合判别在此基础上,划分储层流动单元。对该软件只要修改判别标准和改变数据集内容,可以应用到其他油田。
